Question

我从服务器获取数据：

HttpTransportSE androidhttpTranport = new HttpTransportSE(URL, ContantSystem.TimeOut);
androidhttpTranport.call(SOAP_ACTIONS, envelope);
Object responseBody = responseBody = envelope.getResponse();

我的应用程序显示了一个例外：

我的数据大约是2.4MB（5.000.000个字符）。我的设备的内存是否有限制？为什么呢？

Answer 1

内存限制适用于整个应用，而不仅仅适用于http。因此，您在应用程序的其他地方使用了大量内存，或者您的手机整体内存不足。最有可能是你的应用程序。在您的应用上运行hprof，看看您是否泄漏了引用。信不信由你在大型Java程序中进行内存管理需要花费与C ++一样多的工作量，Android的框架可以很容易地泄漏传递给它的很多对象，就像活动一样。
